Onyx Boox Palma

The Onyx Boox Palma is a fascinating niche device that defies traditional e-reader categorization. It is essentially a 6.13-inch E Ink smartphone, running full Android 11 with cellular connectivity (via SIM card), cameras, and a speaker. Its form factor makes it incredibly pocketable, and the Android OS allows it to run any reading app, news app (like Twitter or Feedly), or even light messaging apps in a eye-friendly format. It's not designed for long-form novel reading as a primary task; instead, it's an 'always-with-you' companion for reading articles, RSS feeds, and short content in bright sunlight, or for reducing smartphone screen time.

Its high price and unconventional purpose make it a specialty tool for tech enthusiasts and those seeking a digital minimalism aid, rather than a mainstream e-reader replacement.
